EXTENSIBLE DEVICE WITH POWER INDICATOR FOR PHYSICAL CULTURE.

Application filed May 18, 1926, Serial No. 109,982, and in Germany May 25, 1925.

My invention relates to an extensible de- Vice for physical culture exercises for developing the muscle, comprising, in combination with a traction spring or the like, a system of pivoting levers, which assures the proper functioning of the device and allows the use of a power indicator, whereby I obtain a marked advantage over the known apparatus in which power indicators cannot be employed.

The following description with reference to the appended drawings which are given by way of example relates to two embodiments of the invention.

Fig. 1 is a front elevation of a constructional form of the apparatus.

Fig. 2 is a like View showing a second form.

1 is a supporting bar to whose ends are pivoted the levers 2- whereof the shorter arms are connected together by the traction spring 8, attached to their ends, and the long arms are provided with handles 5 secured to their ends.

The apparatus comprises a power inclicator consisting of a. fiatbar 6 provided with the hooks or clasps 7 in which is slidable a longer bar 8 carrying a graduated scale for power and a slide 10; the ends of the bars 6 and 8 are pivoted to the long arms of the levers 2 by means of the pins or axles 11 whereby the said power indicator may be readily removed and replaced,

The operation is as follows:

WVhen the handles 10 are brought towards one another, the long arms of the levers will pivot inwardly, and the spring 3 will thus be stretched, thus offering an increasing resistance to the motion which will be shown on the indicator. The slide 10 is displaced to the left by the end of the bar 6 and will remain in this position upon the scale 9 when the levers 2 have returned to their initial position; the force exercised'upon the levers can then be read upon the scale.

Obviously, the said apparatus is susceptible of various modifications or improvements without departing from the spirit of the invention. The traction spring 3 may be replaced by a plurality of springs, for instance two, as shown at 3 (Fig. 2) which are attached at one end to the ends 4 of the levers 2 and at the other end to an intermediate plate 12 secured to the support 1, or I may employ any other suitable elastic resistance device for the same purpose.

Claims- 1. A combined physical culture exercising device and power indicator comprising a bar, handle levers pivoted adjacent their inner ends to the ends of the bar and the handle portions being arranged in substantially the plane of the bar, spring means connecting the short ends of the levers normally maintaining the handle portions of the bars in substantial alignment, and adjustable power indicating means operably connected with each of the handle portions of the levers.

A device as claimed in claim 1, wherein the power indicating means consists of two slidably connected bars the outer ends of which are pivoted respectively to the handle portions of the lever so that the indicator will operate directly with the device.

3. A device as claimed in claim 1, wherein a plate is secured intermediate the ends of the bar, and wherein the spring means consists of two coiled springs the ends of each of which are connected respectively to the plate and to the short portion of the adjacent handle lever.

4. A combined physical culture exercising device and power indicator comprising an elongated relatively straight supporting bar having angularly bent terminals, a pair of handle levers pivoted adjacent the ends to the curved terminals of the supporting bar and having the handle portion opposite and arranged insubstantial alignment with each other and in substantially the plane of the supporting bar, spring means arranged parallel to the supporting bar and connected with the ends of the short portions of the levers, and adjustable power indicating means operatively connected with the handle portions of the levers and normally arranged substantially parallel with the supporting bar, substantially as and for the purposes set forth.

In testimony whereof I afiix my signature.

LUDWIG MEYER.
